ROLLING LAND-SIDE- Application filed December 7, 1921 Serial- No.520,646.

To all whom it man concern:

Be it known that I, THEorHIL s Bnowrv, a citizen of the United States,residing at Moline in the county of Rock Island and State oI Illinois,have invented certain new and useful Improvements in Rolling Landsides,of which the following is a specification, reference being had thereinto the accompanying drawing.

My invention relates to plows and more particularly to the landside partthereof, and has for its object to provide a rolling landside having itscomponent parts assernbled as a unit ready to be secured in place on theplow with the certainty of correct alinement.

Referring to the drawings in which similar numerals indicate identicalparts Figure 1 is a landside elevation of a plow embodying my invention.

Figure 2 is a transverse section on the line 22 of Figure 1. r

Figure 3 is a section on the line of Figure l, and Figure 4 is aperspective view of the rolling landside and its mounting taken from thefurrowward side.

The plow is composed of three principal units; the beam unit, the bodyunit and the rolling landside unit.

The beam unit comprises the beam 1 and the downwardly extending standard.2 adapted to be secured to thebody unit, the

' standard in the instance illustrated being formed by bending a portionof the beam downwardly.

The body unit comprises the frog 4, the moldboard 5, the share 6 and theshort land.- side .7, all rigidly secured together. frog 4 is providedwith a portion t which presents a face to whichthe standard of the beamunit is rigidly secured by suitable bolts. The several parts comprisingthe body unit are manufactured with exactness so that when assembledthey not only fit true with respect to each other, but the face of thefrog portion 4, to which the beam standard attaches, will always be in aplane the exact position of which is predetermined relative to thepoints that determine the base line of the plow body. Distortions of thebeam that may occur during its fabrication due to heating, bending,etc., are corrected so that the beam will occupy its proper positionrelative to the body unit by heating the standard portion 2 and hammer-The ing and fitting it to the predetermined position given the portion 4of the frog "or such correction can well be accomplished by facing thestandard, as indicatedat 3, by a grinding operation so that the beamstandard will have a surface corresponding inposition to thepredetermined position given the face of the portion t of the frog.

The rolling landside unit comprises the bracket 8, the bearing member 9and the circular landside'lO. The bracketS is adapted to be secured tothe plowibo'dy and extends l earwazdly, substantially parallel with theshort landside 7, and its rear portion issecured to thebearing 9, whichrotatably supports the circular landside 10. An ar n 11 rigidly securedto the bearing 9 is bent to extend around the landward face of'thje'landside 10 to form a scraper 12; a scraper 13 for the periphery of therolling landside 10 is bolted to the bend of the arm 11. The bearing9'is mounted on the bracket 8 toposition the rotatable landside 10 sothat is declined toward the wall'of the furrow and contacts therewithatthe bottom of the furrow.

The bracket '8 is preferably made of steel plate, the body portion beingprovided with ribs or corrugations-14 and the edges being turnedoutwardly, as at 15, to stiffen the member {the outwardly turned edgesalso fforn'iing flanges,-best seen in Figured, to enwith and hold thebearing 9. The bracket is formed, as indicated at'16, to

: support the rotatable landside 1Q laterally in proper position withrespect to the short landside portion of the plow body.

lfnoi-der that any one of the rolling landside units, which aremanufactured complete, separate from the plow body units, will attach toany one of the body units and occupy its proper position relative to theplow body, without need for special fitting or adjustment, the forwardportion of the bracket 8 is provided with a face that is p0- sitioned tocorrespond with the predetermined fixed position of the frog portion 4-,regard, of course, being given to the inclination at which the rollinglandside is to stand relative to the furrow wall.

It is therefore apparent that to combine the two units for associateduse, it is only necessary to secure the forward portion of the bracket 8to the frog portion 4 and the parts will be in their correct workingrelationship. My invention makes it possible to attach the rollinglandside unit to the body unit with the same bolts that fasten the beamunit to the body unit, thereby simplifying and lessening the cost of thestruoture.

IV hat I claim is i 1. In a plow, the combination of abeam and standardhaving a positioning surface at its landward side, a plow body, a frogfor attaching the plow body to the standard and having a surface adaptedtofit against and be secured to said positioning surface, a rollinglandside, and a bracket supporting said landside and adapted to overlieand be secured to the landward side of the frog.

2. In a plow, the combination of a beam and standard having apositioning surfaceat its landward side conforming to a predeterminedstandard, a plow body, a frog for attaching the plow body to thestandard and having a surface adapted to fit against and be secured tosaid positioning surface, a rolling landside, and-a bracket supportingsaid landside and adapted to overlie and be secured to the landward sideof the frog.

3. Ina plow, the combination of a beam and standard having a positioningsurface, a plow body, a frog for attaching the plow body to the standardand having a surface adapted to fit against and be secured to saidpositioning surface, a rolling landside, a bracket supporting saidlandside adapted to overlie and be secured to that portion of the frogthat is secured to the standard, and securing means common to thestandard, the frog, and the bracket, for securing said parts together.

4. In a plow, the combination of a beam and standard having apositioning surface at its landward side, a plow body, a'frog forattaching the plow body to the standard and having its surface adaptedto fit against and be secured to the positioning surface of thestandard, a bracket supported solely by the standard, the front end ofsaid bracket being adapted to overlie and be secured to the landwardside of the frog, and a rolling landside journaled onthe rear endportion i of said bracket.

In a plow, the combination with a plow unit comprising a beam andstandard, a plow body, and a frog secured to the plow body and to thestandard, of a rolling land- 6. In a plow, the combination with a plowcomprising a beam and standard, a plow body, and a frog secured to theplow body and to the standard, of a'bracket secured to the standard overa portion of the frog and extending rearwardly therefrom, said bracketbeing bent inwardly at a point back of the standard and havingcorrugations at its bent portion for supporting its rear portion againstdeflection, and a rolling landside journaled on the rear end portion ofsaid bracket.

7. In a plow, the combination with a plow comprising a beam andstandard, a plow body, and a frog secured to the plow body and tothe'standard, of a bracket secured at its forward end to the standardover the frog and extending rearwardly therefrom, the rear end portionof said bracket being unsupported and being offset toward the furrowside of the plow, and a rolling landside journaled on the rear endportion of said bracket.

8. In a plow, the combination of a beam and standard, a plow body havinga frog secured to the standard at the landward side thereof, a rotarylandside, and a support for the rotary landside overlying and secured tothe landward side of the frog.

9. In a plow, the combination of a beam and standard, a plow body havinga frog secured to the standard at the landward side thereof, a rotarylandside, a support for the rotary landside secured to the landward sideof the frog, and securing means for said support common to said frog andstandard.
